Why Get Tested?
To help diagnose and distinguish between autoimmune disorders
When to Get Tested?
When your ANA (Antinuclear Antibody) test is positive; when you have symptoms that suggest an autoimmune disorder
Sample Required?
A blood sample drawn from a vein in your arm
How is it used?
The ENA panel is usually ordered following a positive ANA test in people who have clinical signs of an autoimmune disorder. The 4-test ENA panel is used to help diagnose mixed connective tissue disease (MCTD), systemic lupus erythematosus (SLE), and Sjögren's syndrome. The 6-test ENA can also help identify scleroderma and polymyositis.

An ENA panel may also be ordered if a doctor suspects that a person with a known autoimmune disorder has developed an additional disorder.
